w6c_ww and wwdump_ww (-c mode) silently passed source into cgen without type-checking it; any type error flowed through as broken asm with exit 0. Mirror cstage cmd/w6c/main.c:73-75: between the parse-error gate and cgeninit, install typesinit + checkinit + checkfile + `if (ck.errs > 0) return 1;`. Cgen path unchanged — drivers own check, cgen owns emit (checkfile not idempotent due to installdecl scopedefine). The wire-up was blocked by five latent check.ww divergences from cstage, all landed first: cross-module type refs (#51), enum-int reinterprets (#52), per-block scoping (#53), nominal-first tagged-variant inclusion (#55), and same-module N_IDENT callee preference (#56). With those clear, the broader exercise of check across every selfhost driver reaches 131/131 first try. 994_w6c_ww grows by one row: a trivially-wrong `let x: i32 = "hello";` smoke pins both stages to exit-non-zero. Pre-#50 it emitted 202 bytes of broken asm with exit=0. Unblocks #42 (size/align/offset wwstage intercepts) and the audit-§1.8 UP-polarity refactor (node.type_ population can now land in the same check pass we just wired up).
